A conditioning unit, comprising:

• an enclosure having two opposing exterior walls;
• a gas delivery device positioned adjacent to an exterior wall;
• at least one exterior wall comprising a port, the port extending into a portion of the at least one exterior wall to direct gas or air from the gas delivery device;
• a pair of movable surfaces, the pair of movable surfaces extending in the longitudinal direction, the pair of movable surfaces being positioned between the two opposing exterior walls;
• wherein the pair of movable surfaces are configured to uniformly distribute powder placed across a surface of the pair of movable surfaces;
• and
• wherein the enclosure is positioned near an outlet of a funnel;
